NCP345SNT1G is a mixed technology transient voltage suppressor (TVS) from ON Semiconductor. It is designed for protecting high voltage circuits from unexpected voltage transients. This device has a wide operational range of 6 V to 16 V, and operates at a maximum power dissipation of 500 mW. It is also available in a wide variety of package styles.

The NCP345SNT1G is a low capacitance, highly reliable, and low operating voltage TVS. It has a switching threshold voltage of 36 V and a leakage current of less than 0.5 μA. It also features integrated ESD protection and short-circuit protection. This TVS is manufactured in an advanced CMOS process and is designed to meet the harsh environment of automotive applications. Its advanced design and low on-state resistance minimize power consumption in high EMI environments.

The key features of the NCP345SNT1G include a highly compact form factor, low internal capacitance, fast switching speeds, low power consumption, and an open drain output. This device is ideal for automotive electronic control units (ECUs) or system-level applications, such as powertrain and body controllers. It is also suitable for use in commercial and industrial systems, including consumer electronics.

The working principle of the NCP345SNT1G is based on a unique TVS diode array design that provides two paths of protection. The first path utilizes an N-type TVS diode that has an ESD clamp structure. This structure allows the device to absorb and redirect electrostatic discharge (ESD) currents. The second path utilizes a P-type TVS diode that operates in a “crowbar” mode to protect against overvoltage conditions. The P-type diode effectively lowers the voltage until it reaches a safe level, at which point it turns off and allows normal circuit operation.

The NCP345SNT1G is designed to operate in temperatures ranging from -40°C to +125°C, making it an ideal choice for automotive applications. It is also RoHS compliant, making it suitable for use in a wide variety of applications. With its high level of protection, reliability, and ease of use, the NCP345SNT1G is an excellent choice for automotive, commercial, and industrial applications.
